CRlMPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 520,097, dated May 22,1894. Application filed February 21,1894. SerialNo. 500.978-- (Nomodel-To to whom it may concern.-

Beit known that I, GAsPAR WAGNER, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee, and in the State ofWisconsin, have invented certain new and useful Improvements inCrimping- Machines; and I do hereby declare that the following is afull, clear, and exact descrip tion thereof.

My invention has for its object to provide a simple, economical machinefor the purpose of facilitating the creasing, stretching and smoothingof boot and shoe uppers; the same consisting in certain peculiarities ofconstruction and combination of parts hereinafter specified withreference to the accompanying drawings and subsequently claimed.

In the drawings: Figurel represents a plan view of my machine partlybroken away; Fig. 2, a vertical longitudinal section taken on line 2-2of the preceding figure; Fig. 3, a detail plan of the front portion ofthe machine as it appears with certain of the parts detached; Figs. 4and 5 sections respectively taken on lines 4et and 5-5 of the firstfigure; Fig. 6, a plan view of a boot upper before being worked upon themachine, and Fig. 7, a perspective view of a slicker employed inconnection with said machine.

Referring by letters to the drawings A represents the frame of myimproved machine embodying parallel longitudinal guide-beams B, andtransverse guide-braces O that connect said beams, the latter and thebraces being at the front of the machine as clearly illustrated in Fig.1.

In rear of the guide beams B, some distance therefrom and parallelthereto is another beam or plate D having a ledge 17 at its frontthroughout its length. The longitudinal guide-beams B are looselyengaged by ribs that extend from carriers in the form of blocks E havingledge-plates F fast thereon. The aforesaid carriers are controlled as tomovement longitudinally of the guide-beams B, by screws G that turnloose in the transverse guide-braces C and the ends of themachine-frame. Another screw I turns loose in the guide-beams B andcontrols the move ment of a carrier in loose engagement with thetransverse guide-braces O, the latter carrier being herein shown ascomprising a central screw-engaging block J and barsK bolted orotherwise suitably secured to the upper and lower sides of said block.Fast on the latter carrier is a plate L having three edges thereofprovided with a continuous ledge c of suitable contour, and it ispreferable to have this plate detachably connected to its carrier bybolts and nuts or other suitable means.

' The ledge-plate D and either of the ledgeplates F serve as normalsupports for a pattern-plate M over which a boot or shoe upper. N isfolded, and the ledge on the plate L is of such contour as to have bothends match said pattern-plate and also support the same and an upperthereon. The upper being positioned on the pattern and in place on themachine, at either end of the latter, the proper one of the screws G andthe screw I are adjusted to clamp said pattern in place,

as well as to set the crease in said upper.

This operation having been accomplished, the foot portion of the upperis caught in grips having pivotal and longitudinal adjustment at thecorners of the machine frame. As herein shown each grip comprises a pairof jaws O hinged to a rod P and impinged by an interposed spiral-spring(Z loose on a screwpin e that rises from the under jaw to engage theupper jaw, a set-nut 9 being run on the outer end of said pin to clampsaid jaws together on the upper against the resistance of said spring.The rod P is loose in upturned ends of a plate Q supported on thelongitudinally slotted upper portion of a bracket R made fast to acorner of the machine frame to extend outward therefrom. The bracketslotand adjacent plate are engaged by a bolt it that receives a set-nut 2',whereby said plate may be held in longitudinal adjustment at any angle,and the outer end of the rod P'is screw-threaded to engage a hand-nut Semployed to efiect a draw on the grip that is hinged to said rod,whereby slack in the upper may be taken up in any direction at the willof the operator when said upper is stretched bythe manipulation. of aslicker thereon, the latter tool being shown by Fig. 7. One side of theupper having been smoothed and stretched, the pattern-plate isunclamped, turned over in a longitudinal direction and reclamped, afterwhich the upper is gripped and manipulated in a manner similar to thatabove specified, whereby the creasing, stretching and smoothing of saidupper are completed.

As the pattern-plates for boot and shoe uppers are variable, a series ofinterchangeable ledge-plates L, corresponding to said patternplates, mayaccompany each machine, and the width of the rear ledge-plate D may bevaried by making the same in sections if found necessary or desirable.

Having now described myinvention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. A crimping-machine comprising a suitable framehaving parallellongitudinal guidebeams and transverse guide-braces connecting the same,carriers adjustable on said beams and braces, ledge-plates supported onthe carriers, another ledge-plate in rear of the guide-beams, anupper-supporting pattern-plate for clamp-engagement with theledge-plates, and pivotal longitudinally adjustable grips connected tothe machineframe, substantially as set forth.

- 2. A'crimping-mac hine comprising a suitable frame having a stationaryrear support, other supports adjustable longitudinally of the frame'ateach end thereof, a carrier adjustable transversely of said frame, a.creasing-plate detachably connected to the carrier, 30 an upper engagingpattern-plate for clampengagement between the stationary support, one ofthe adjustable supports and the creasing-plate; and upper-grips adjustably connected to said frame, substantially as set 35 forth.

3. A crimping-machine comprising a. suitable frame provided withdiverging longitudinall y slotted corner brackets, bearings havingset-bolt and nut connection with slotted por- 4o tions of the brackets,rods longitudinally adjustable in the bearings, upper-grips connected tothe rods, stationary and adjustable supports on said frame, and an upperengaging pattern-plate for'olamp engagement with 5 said supports, andcreasing-plate, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wis- 50 cousin, inthe'presence of two witnesses.
